Fire foam tank manufacturer Large capacity cubic foam tank price Factory fire foam tank model

Description :

　　1. Classification and model of pressure type foam proportioning device

　　The pressure type foam proportioning device is used to store foam extinguishing agent

　　The function of the mixer is to replace the foam extinguishing agent stored in the fire water supply device and match it with the water supply

　　A device for mixing to form a foam mixture at a fixed proportion The pressure type foam proportioning device widely applies

　　Used for: liquid, liquid and semi liquid spraying foam extinguishing system, foam sprinkler extinguishing system, or

　　It is a mixing liquid supply device for foam gun or foam gun.

　　2. Classification

　　Pressure type foam proportioning devices usually have the following classification methods:

　　According to the storage form of foam concentrate, it can be divided into proportional mixing device and non proportional mixing device:

　　According to the structural form of the storage tank, it can be divided into horizontal proportional mixing device and vertical proportional mixing device;

　　According to the number of proportional mixers, they can be divided into single proportional mixer mixing devices and multi proportional mixer (2 or 4) mixing devices.

　　3. Model and parameters

　　"PHY": pressure type foam proportioning device

　　'M': indicates that those with M are diaphragm type, and those without M are non diaphragm type

　　"L": Additional feature: indicates that the L band is vertical, not marked as horizontal

　　The middle number represents the main parameter flow rate, L/S

　　- ": indicates the number of proportional mixers

　　The following figure: represents the foam liquid reserve of the device

　　For example: PHYM (L) 32-30 model of vertical pressure foam proportioning device

　　Model of PHYM32-30 Horizontal Pressure Full Clear Proportional Mixing Device

　　【working principle】

　　The pressure type foam proportioning device is mainly composed of a foam liquid pressure storage tank and a PHY type pressure type proportioner made by using the Venturi principle. When the water flow in the system pipe network passes through the pressure reducing orifice plate of the proportioner, a pressure difference will be formed before and after the orifice plate. Part of the water (3% or 6%) at the high pressure enters the foam tank through the water inlet pipe of the foam tank and is squeezed. The foam liquid in the tank is squeezed through the liquid outlet pipe of the foam tank to the low pressure of the proportioner and mixed with water to form foam mixture. The formed foam mixture is output to the foam production equipment and mixed with air to produce foam.

　　【Product Features】

　　1. The foam mixing ratio is accurate and reliable, the sprayed foam liquid has strong penetration ability and high fire extinguishing efficiency.

　　2. The unused foam liquid can be used continuously to save foam liquid and reduce costs.

　　3. It has a wide scope of application, and can be used for high, medium and low expansion foam extinguishing agents.

　　Installation and usage instructions

　　【 Installation of the device】

　　The direction of pressure water flow during installation should be consistent with the direction indicated by the arrow on the proportional mixer on the device. Pressure gauges, one-way valves, control valves, pipeline filters, etc. should be installed before the proportioning mixer;

　　The foam tank shall be fixed with the ground foundation.

　　【Filling method of foam concentrate】

　　Close all valves, open two exhaust valves, fill 1/3 to 1/2 of the tank water between the tank and the tank through the water inlet pipe and the drain port, then open the liquid filling port, insert an inch rubber pipe from the liquid filling port to the tank bottom, inject foam extinguishing agent into the tank through the crossover pipe, open the drain valve after water is discharged from the exhaust port, and drain water at a flow similar to the flow of foam liquid filling until the foam liquid is fully filled. After filling is completed, close the filling port and drainage valve, open the inlet valve, and slowly fill the space between the tank and the tank with water until water flows out from the exhaust port. Close the exhaust valve and inlet valve, and then rinse the scattered fire extinguishing agent outside the device with clean water.
